Test principle of 45 degree combustion tester

Author:QINSUN Released in:2023-10 Click:55

45 degree combustion tester is a testing equipment independently developed and produced by qisnun Precision Electromechanical Technology Co., Ltd. It is mainly used to measure the flame retardant properties of clothing fabrics, decorative fabrics, tent fabrics, etc. consists of a control system and a combustion chamber. The sample is installed on a sample holder inclined at 45° in the combustion chamber. Move the burner closer to the sample. Use the flame to ignite the sample for a specified time, then return. Observe the combustion state of the sample and the speed of flame propagation on the sample. , evaluate the flammability and flame propagation performance of the sample.

Complies with standards:

ASTM D 1230 FTMS 191-5908 CFR 16 Part 1610, CALIF TB 117 NFPA 702 GB/T 14644

Test principle:

1. Int testdensity and burning rate

Under the specified conditions, place the sample at an angle of 45°. ,ignite the sample for 1 second, and the time required for the sample to burn upward with a flame for a certain distance is used as a measure to assess the severity of textile combustion. For tissues with raised surfaces, inflammation or melting of the base tissue serves as an additional indicator of burn severity.

2. Damage area and damage length test

Under the specified test conditions, ignite the textile sample in the direction of 45° and measure the post time -combustion and slow combustion of the tissue after combustion. . Damage area and damage length.

3. Contact flame number test

Under the specified test conditions, ignite the textile sample in the direction of 45° and measure the number of times the doi fabrict get in touch. the flame at a distance of 90 mm from the lower end of the sample. .

Shanghai Fanbiao Textile Testing Technology Co., Ltd., as an enterprise integrating R&D, manufacturing, sales, training and service, is committed to bringing a larger number of testing instruments and long-term supply of textiles, leather, testing instruments for combustion, automobile interior materials, environmental climate aging, masks and protective clothing, etc. . can also be customized to meet non-standard requirements.
